‘The Guitar Collection: George Harrison’ is a joint project from the estate of the late Beatles legend and Bandwith Publishing. The app, which will cost $9.99, features 360-degree imaging by photographer Steven Sebring that allows users to see each item from the private collection in great detail. The stories behind each guitar — the circumstances of their acquisition and the significance of the modifications Harrison made — are well documented.

Adding to the app’s appeal are Harrison songs that are categorized by the guitars he used on each recording, as well as Harrison audio clips that serve as introductions to many of the instruments.

Tom Petty and the Heartbreakers guitarist Mike Campbell, as well as Harrison’s son, Dhani, are among the musicians who are featured in the app’s video section playing some of the guitars.
